Application ned April 27, 1906. saai No. 313,923.

To all whom, it may/ concern- Be it known that I, WINTWORTH V. LAN; DER, a citizen of the United States, and a resident of Newton, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Chlorination Apparatus, of which the following is a specification.

My invention relates to apparatus for the chlorination of ores; and it consists in sundry improvements in such apparatus by which I obtain increased ellieiency and saving in materials, labor, and power.

My apparatus is suited to and in most cases involves 'the performance of an 'improved process of ore chlorination, which for the sake of illustration will be described hereinbelow. This process forms the subjectmatter of an4 application for Letters Patent of the United States, Serial No. 313,922, iiled by me concurrently herewith and is expressly reserved for claim therein.

In the drawing hereto annexed my improved apparatus is illustrated in longitudinal section.

In the drawing, A represents a head-chamber into which comminuted ore is delivered, as from a'superposed hopper ll. The bottom ol this head-chamber terminates in a lip or dry Weir at A., over which the ore is delivered in a cascade upon the rille presently to b e described. The orc-feed may be secured in a number of dill'erent ways. The

mode which l prefer is, as illustrated, to provide a feed-screw G, projecting into the. headchamber A and driven by some. suitable appliance, as the pulley l on the. outside. I his head-cham )er together with the hopper above it are proportioned with relation to the character and degree of eomminution of the mass of' ore-carrying earth orroek to be treated, so that so long as the supply is maintained in the hopp( r ll the head-chamber A will be completely lull from base to top, and it will thus bedllicult, if not impossible, for any gases within the vapparat-usn to escape by backing up through the headchamber and ,ho per. Below the delivery end of the hem-chamber A, I arrange, a water-intake chamber F2, which receives water through the pipe F, preferably through a strainer-plate F', which will serve to distribute thc stream and prevent undue disturbances or gushes of liquid from the pipe F. To the delivery ends of the head-chamsealed, as by burning and ber A and water-intake F21 secure the upper section-.Bof the sectional ritlle-pipe, ma ing a gas-tight joint. The sections B of the riilepipes are composed, preferably, of glazed tile or other refractory earthenware which will eli'eetually resist the attacks of chlorin, and, moreover, I prefer to employ pipe-sections B which are square in cross-section. Each of the sections B is joined and hermetieally sealed to its neighbor, as by the flanges B', and in the tops of each ofthese sections B are provided tightly-covered hand-holes, as at BZ. When the sections B are assembled, they form an inclined pipe, the angle of inclination being about one foot in ten. Each pipe-section B isprovided with a ritHe-plate C, which, like the pipe, should'be constructed of refractory material, as glazed tile and glazing, to t e interior of the pipe-section itself. The riies when the apparatus is in position are set at' a slight angle to the axis of the pipe, so that each ritlle is nearly horizont-al, just enough inclination beinggiven to it to oll'sct the frictionbe'tween a stream of liquid running over the plate and the plate itself, so that the stream may be as nearly as possible of uniiorm depth. Each ,rillle-plate C is provided with transverse corrugations or ridges, as E, and projects a slight distance. beyond the end of the pipe-section, as at l). A rilIlc-pipe of this character extending for about 'fifty feet Will probably be sullieient for all practical purposes, although l consider it desirable to extend this pipe considerablr l'arthcr and to make it in some, instances at least two hundred'feet. in length. lhe length of' the pipe will be determined for eaeh ease according to the nature of thel ore and the concentration of chlorinated water. lCach section Il need not be longer than eighteen inches, so that thereI will bc in the pipe when assembled a llarge number of riflle-sections, each overhangin(r the next, as at the points marked l) in the drawing.

.,Thenlower or delivery section ol' thel ritllcpipe. deliversinte-thelrfeiyiig-tank K. Mea-ns should bel provided wherebyd'he rceeiving-tank K shall be gas-tight with theV rilll'e-pipe, and for this purpose l have indicated the construction ol' the. hood Ii', which slips over the delivery end of the rlle-pipe and may be sea-led thereto, as by a rubber gasket or packing-ring. The, tank K should, moreover, be removable or capable of discon- IOO IlO

netion from the riile-pi e B, and for this purpose I have indicate the arrangement shown in the drawing-namely, rails or runways L, uponwhich the tank K is mounted by means of small wheels or rifiles K5. The runway L is also mounted on trucks, as at L', so that it may be removed with the tank trans- V"verselif to theaxisf of the rifliQ/zlpe itself' H the tanks used are too large for vsuchmanipulation, the'connections may be by large rubber hose-pipe. 'In order to provide means to sample the liquor in the tank K, I show in A ter may have been chlorinated by a process of preliminary preparation, or clear-that is to say, unchlorinated-water maybe brought through the pipe F and a stream of chlorin gas, as through the pipe M, mingled therewith just before it enters the ore-chlorinating, apparatus. The ore and chlorinated water mingled at the head of the rifiie-pipe will proceed. as one streamrbeing agitated by the riffle-ridges E and still further agitated by falling'incascades from one rifIie-plate to the other, as at the oints4 marked D, until iinally the solution fal s from the delivery end of the.

lowest riiiie-plate in the series into the tank K. If the chlorinated water entering the apparatus carries chlorin in sufliciently concentrated solution, an atmosphe1l -fhlorin will be maintained ,thereby in the rinde-pipes. The presence and maintenance of this atmosphere is of value in the process, for the reason that as the chlorinated water becomes exhausted or depleted by its reaction upon the soluble ortions of the ore. it has an opportunity by eing agitated in the presence of and falling in occasional cascades through this atmosphere of chlorin to become regenerated and reinforced during the continuance of the chlorination process itself so that the chlorinated water is to all practical intents and purposes just as vigorous at the lower end of the series of riflie-plates as, it is at the head. This renders the chlorin ac- .tion eiective at all stages and promotesftle solution-of the smaller and smaller'residues of soluble matter. The insoluble portions of the massl of metal containing earth or rock are detained by the linie-plates and retarded and classified according to theirusize, specific gravity, &c. The rooves between the rifiie-ridges gradually fil-u withl these insoluble concentrates, the lling proceeding gradually'from the head of the rie-pipe tolikewise clears the riffle -pipeof its chlorin.

atmosphere. When this last cleaning operation is inished, the receiving-tank is removed from`iftsfconneetion-withtherifflepipeshch may in turn be connected by any suitable means to a wash-tank. The uppermost hand-hole B2 is then opened and a vigorous stream of water (as by a hose) is turned into the riHe-pipe and the rifiie washed out, the concentrates being sent down the pipe. By washing successively in this' way through each of the hand-holes B2 the concentrates are deposited in the wash-tank. The subsequent treatment of the chlorids in the receiving-tank and of the concentrates in the wash-tank will depend upon the requirements of 'each particular operator and need not differ from the processes now in vogue.

The above-described process has the advantage of being continuously and uniformly eiiective during the whole period between charging and discharging the apparatus. By

connecting the receiving-tank with suitable chlorinating-towers or gas-tanks the residues of chlorin gas ,from the process may readily be saved to be used over again, so thatby continuous operation in rotation by several such apparatus as above described an economical and eifective cycle can be maintained. Moreover, all the discomfort and danger to workmen from the escape of chlorin-gas is eliminated by the coniinement of the gas in a continuous closed system, which is not opened to the air until all chlorin gas has been washed out.
